#!/usr/bin/env bash
#
# Oppi installer (repo-root wrapper + curl-pipe bootstrap)
#
# Supports two modes:
# 1) Run from repo root: delegates to server/setup.sh
# 2) Run via curl|bash: clones/updates repo, then runs server/setup.sh
#
# Usage:
#   bash install.sh            # install deps, build, start foreground
#   bash install.sh --install  # install as macOS LaunchAgent service
#
# Optional env vars (curl|bash mode):
#   OPPI_REPO_URL      (default: https://github.com/duh17/oppi.git)
#   OPPI_REF           (default: main)
#   OPPI_INSTALL_DIR   (default: $HOME/oppi)
